How does a cooled thermal imager work to detect and capture thermal images with high precision and accuracy?

A cooled thermal imager works by using a special sensor that can detect infrared radiation emitted by objects. The sensor is kept at a very low temperature to improve its sensitivity and accuracy. When an object emits infrared radiation, the sensor detects it and converts it into an image based on the temperature differences. This allows the imager to capture thermal images with high precision and accuracy.
